i bought a 83 gl and sometimes it has smoking fits. did it when it first started then the next time it simply went away. round the block afew times and nothing.yet this morning on its second run,it started again. when it does it, its raw thick clouds. any thoughts?

thanks, ken

First - does the smoke smell sweet like coolant? Or like burn oil?

 

Is it an automatic? If so, there is a modulator valve on the tranny that can suck tranny fuild into the intake...

 

Check the PCV system, and check for coolant loss...

 

Check the oil for water contamination, and the coolant for oil floating in it...

 

If none of those check out, run a compression check to be sure, and then go after the carb base gaskets, and the intake manifold gaskets - those can leak coolant directly into the intake.
